Hi Mark,
Hi Mark,
Thanks for the response!
The UDAFPercentile.java have two terminate() methods since it is handling
two different input types by the two inner classes: PercentileLongEvaluator
and PercentileLongArrayEvaluator.
I am handling only a single input type of double from one table column to
the it
Hi Mark,
Sorry for the preliminary questions since I am a beginner for Hive.
I have read in both books (Hadoop Definitive Guide and Programming Hive)
that we need to implement the functions: init(), iterate(),
terminatePartial(), merge() and terminate for extending a UDAF and
UDAFEvaluator class.
Hi Abhishek,
The code looks incomplete.

Those are all the methods your UDAF class needs to implement but you seem
to be missing them.

Look at
https://github.com/apache/hive/blob/trunk/ql/src/java/org/apache/hadoop/hive/ql/udf/UDAFPercentile.javafor
reference. It has two terminate()'s - one for UDAF and one for the
Evaluator.
Do you mind posting your complete code on github somewhe
